5 DHT Sensors

[JademicIT]

Hi,
I'm using 5 AM2302 sensors connected all togheter to an NODEMCU V2 board.
It seems work for a couple of days, after this period the 4 and 5 sensors shows NAN, the only way is to switch off and on again.
I tried with 4 different esp mega FW.
I tried to connect through usb and also with VCC direct to Sensors.
My actual Fw is mega-20200328

Do you have any idea?

Hi,

For any analysis we need a bit more info:

How have you connected the sensors to the NodeMCU board? (See this ESPEasy github issue for more info)
What ESPEasy plugin are you using?

As 20200328 is less then 1 day old, how long has it been tested on that release?

Last Fw I uploaded today and couple of Hs later was already in NAN, I hade restarted this morning all the system (switch-off, than on again).
Before today I used the one of 10 march Fw (until this morning), before was the 02 February Fw, than before was the 08 dec. 2019.
I attached the screen page where to see the device connection and GPIO used.

I'm not sure this plugin is capable of running multiple instances on the same node.

it can.

about one year ago it was not possible and the there was an update.
i have running 3 Sensors at one NodeMCU since one year BUT!
i had also trouble with DHT sensors and it came all down to resistors capacitors and cable!
It was a hard way to learn about electronic components.
on a breadbord it was working all perfect, but in the real hard world it was totally different

May i ask which cable and sensors you use and how long it is ?

3.3V for example was too weak in my enviroment (about 30 meter cable)
so i used an levelshifter to support sensors with 5V plus an capacitor right before the sensor

For the moment is only a work in progress, so I have only 15cm. cable and I'm using 5V.
The sensor is this:

The first 3 sensors works always, only the last 2 sensors show, after a couple of days, NaN.

Ah now I remember indeed.

The fifth sensor is already in NaN
